First-degree atrioventricular block (AV block) is a disease of the electrical conduction system of the heart in which electrical impulses conduct from the cardiac atria to the ventricles through the atrioventricular node (AV node) more slowly than normal.

Feb 19, 2025 · First-degree ventricular (heart) block affects the electrical signal that makes the heart beat. It causes a delay in a portion of the heart beat and may lead to a slow heart beat....

Apr 14, 2024 · Type I, also called Mobitz Type I or Wenckebach’s AV block: This is a less serious form of second-degree heart block. The electrical signal gets slower and slower until your heart actually skips a beat.

Learn about first-degree AV block (AV block 1), with emphasis on ECG diagnosis, clinical characteristics, differential diagnosis, management and treatment.

Jun 11, 2024 · Review of first degree AV block with some ECG examples - PR interval > 200ms (five small squares) LITFL ECG Library

Jan 19, 2023 · First-degree atrioventricular (AV) block is a condition of abnormally slow conduction through the AV node. It is defined by electrocardiogram (ECG) changes that include a PR interval of greater than 0.20 without disruption of atrial to ventricular conduction. This condition is generally asymptomatic and discovered only on routine ECG.

Learn about cardiac arrhythmia first-degree atrioventricular (AV) block. Study the ECG characteristics, symptoms, causes, and treatment with ACLS guidelines.

Atrioventricular (AV) block is defined as a delay or interruption in the transmission of an impulse from the atria to the ventricles due to an anatomic or functional impairment in the conduction system.

Atrioventricular block (AV block) is a type of heart block that occurs when the electrical signal traveling from the atria, or the upper chambers of the heart, to ventricles, or the lower chambers of the heart, is impaired.

Atrioventricular block represents a delay or disturbance in the transmission of an impulse from the atria to the ventricles. This can be due to an anatomical or functional impairment in the heart’s conduction system.
